  1. Dear chaps,

    I have a problem. I have a signal recorded from a ultrasonic
    transducer of a chemical reaction. It is rich of noise, expecially the
    white one. I tried to filter with normal filter (butterworth band
    pass), but I did not obtained a lot of success.
    So, I thought was better delete the White gaussian noise with an
    adaptive filter. I used the demo of Simuling of LMS but I have
    problems to "create" the noise artificially?
    What can I do? Which information I need to identify it?
    Is it enought to record the noise from the becker without reaction?

    Does it work or I must think about a different filter?

    Thanks in advance!
    Manuel
